You can try something like this:

timedOutFuture = after(duration = duration, using = system.scheduler) {
   Future.successfull(None)
 }

Future.firstCompletedOf(Seq(youHttpRequestFuture, timedOutFuture))

Hope it helps

So I suppose you are trying to solve 2 problems. How to define a particular timeout in the configuration and then how to manage timeouts when they happen.

  • Define http client timeouts: You will need to update your application.conf to overwrite the default configuration of the http client. e.g.:

    spray.can {
      client {
        request-timeout = 20s
      }
    }
    
  • Managing timeouts: When you use the spray client, you will use a pipeline that will run the requests. It will be a function that looks something like (HttpRequest) => Future[ObjectResponse]. The result will be a Future of an object you have defined ,ObjectResponse in my example, you can resolve the future. In case a there is a timeout, the Future will become a RequestTimeoutException. Then you will be able to process the timeout exception with a recover. So your code will look something like this:

    def sendRequestFunction(...): Future[ObjectResponse] = {...}
    
    sendRequestFunction(parameters) map (Option) // In case we get an object, we will have a Some(obj)
    recover {
       case e: RequestTimeoutException => None
    }
